       5. The connector according to  claim 2 , wherein, of the lateral wall, an end portion on a side on which the opening is situated in the fitting direction is provided with a flange portion extending toward an outside of the frame, and
 wherein the flange portion is seamlessly joined to a portion extending in the fitting direction in the lateral wall. 
 
     
     
       6. The connector according to  claim 1 , wherein the blocking portion is disposed between the first terminal and the second terminal in an intersecting direction intersecting a fitting direction, in the fitting direction the connector and the counter connector being fitted with each other, and
 wherein, in the intersecting direction, an end surface of the fitting portion and an end surface of the attachment portion are coplanar with each other. 
 
     
     
       7. The connector according to  claim 1 , wherein the fitting portion enters a recess portion provided to the counter blocking portion to be thereby fitted with the counter blocking portion,
 wherein the attachment portion includes an insertion recess portion into which part of the housing is inserted, and a press-fit portion protruding from an inner lateral surface of the insertion recess portion, and 
 wherein the press-fit portion is press-fitted to the part of the housing, the part having been inserted into the insertion recess portion. 
 
     
     
       8. The connector according to  claim 1 , wherein the frame is conductive,
 wherein the first terminal and the second terminal are high-frequency signal transmitting terminals, 
 wherein, in the inside of the frame, a third terminal which is a low-frequency signal transmitting terminal is additionally disposed between the first terminal and the second terminal, and 
 wherein the blocking portion is disposed each between the first terminal and the third terminal and between the second terminal and the third terminal. 
 
     
     
       9. The connector according to  claim 1 , wherein the blocking portion is connected to a ground potential. 
     
     
       10. The connector according to  claim 3 , wherein, of the lateral wall, an end portion on a side on which the opening is situated in the fitting direction is provided with a flange portion extending toward an outside of the frame, and
 wherein the flange portion is seamlessly joined to a portion extending in the fitting direction in the lateral wall. 
 
     
     
       11. The connector according to  claim 4 , wherein, of the lateral wall, an end portion on a side on which the opening is situated in the fitting direction is provided with a flange portion extending toward an outside of the frame, and
